Abstract (en)
[origin: EP0389999A2] The present invention provides an apparatus and a method for managing as the file on the computer the data such as moving pictures and audio which are demanded to be inputted, outputted at the real-time. In the conventional file apparatus, the data were composed of the discrete blocks of the fixed capacity. The present invention manages the blocks as the compound body of significant data and blank data, normally manages the amount of the significant data within the block into the capacity or more which is determined by the transfer speed of the data to be handled, the performance of the storage media, and so on so that the high speed property of the edition by the discrete block style and the real-time contiguous input-output of the data may be realized at the same time.
